    That's pretty good if you are only losing 200 from top to bottom. It might be too much to start with. For some reason, the PAR of LEDs are slightly higher than what is read by a PAR meter. To acclimate your tank, I would turn them down a little.

    I didn't realize you have had them for that long. If your corals have responded favorably, crank it up some more if you want.

    Minimum Par needed on the sandbed is 100 micromoles per meter square per second(shrooms, etc). From there Par should increase as you go up. I'd place the clams higher (gradually) as they require higher Par than 100.
